The present disclosure relates generally to the management of short message service (SMS) functions in a telecommunication network.

2. Description of Related Art

To meet the demand for wireless data. traffic having increased since deployment of 4G communication systems, efforts have been made to develop an improved 5G or pre-5G communication system. Therefore, the 5G or pre-5G communication system is also called a. ‘beyond 4G network’ or a ‘post LTE system’. The 5G communication system is considered to be implemented in higher frequency (mmWave) bands, e.g., 60 GHz bands, so as to accomplish higher data rates. To decrease propagation loss of the radio waves and increase the transmission distance, the beamforming, massive multiple-input multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, an analog beam forming, large scale antenna techniques are discussed in 5G communication systems. In addition, in 5G communication systems, development for system network improvement is under way based on advanced small cells, cloud radio access networks (RANs), ultra-dense networks, device-to-device (D2D) communication, wireless backhaul, moving network, cooperative communication, coordinated multi-points (CoMP), reception-end interference cancellation and the like. In the 5G system, hybrid FSK and QAM modulation (FQAM) and sliding window superposition coding (SWSC) as an advanced coding modulation (ACM), and filter bank multi carrier (FBMC), non-orthogonal multiple access (NOMA), and sparse code multiple access (SCMA) as an advanced access technology have been developed.

The Internet, which is a human centered connectivity network where humans generate and consume information, is now evolving to the Internet of things (IoT) where distributed entities, such as things, exchange and process information without human intervention. The Internet of everything (IoE), which is a combination of the IoT technology and the Big Data processing technology through connection with a cloud server, has emerged. As technology elements, such as “sensing technology”, “wired/wireless communication and network infrastructure”, “service interface technology”, and “Security technology” have been demanded for IoT implementation, a sensor network, a machine-to-machine (M2M) communication, machine type communication (MTC), and so forth have been recently researched. Such an IoT environment may provide intelligent Internet technology services that create a new value to human life by collecting and analyzing data generated among connected things. IoT may be applied to a variety of fields including smart home, smart building, smart city, smart car or connected cars, smart grid, health care, smart appliances and advanced medical services through convergence and combination between existing information technology (IT) and various industrial applications.

In line with this, various attempts have been made to apply 5G communication systems to IoT networks. For example, technologies such as a sensor network, MTC, and M2M communication may be implemented by beamforming, and array antennas. Application of a cloud RAN as the above-described big data processing technology may also be considered to be as an example of convergence between the 5G technology and the IoT technology.

In earlier cellular telecommunication systems, such as global system for mobile communication (GSM), the ability to send SMS messages from a mobile device was a function that was always available. As such, no special configuration was required. In the fifth generation (5G) system, the use of SMS is optional and is requested specifically by the user equipment (UE).

A UE registers its desire to use the SMS over the non-access stratum (NAS) during initial registration and can modify its desire to use the SMS during mobility registration. NAS is a functional layer in the universal mobile telecommunications system (UMTS) and long-term evolution (LTE) wireless telecom protocol stacks between the core network and user equipment. This layer is used to manage the establishment of communication sessions and for maintaining continuous communications with the user equipment as it moves.

The access and mobility management function (AMF) allocates an SMS function (SMSF) to the UE and requests the SMSF to activate the SMS service if the UE is subscribed to the SMS service. Either the UE or AMF can deregister the UE from using the SMS as specified in the applicable standards if the UE indicates to AMF that it no longer wants to send and receive the SMS over NAS (e.g., not including “SMS supported” indication in a subsequent registration request message) or if AMF considers that the UE is deregistered or if AMF receives deregistration notification from unified data management (UDM) indicating UE initial registration, subscription withdrawn or 5GS to evolved packet system (EPS) mobility as specified in the applicable standard, AMF invokes Nsmsf_SMService_Deactivate service operation to trigger the release of UE context for SMS on SMSF based on local configurations.

If the UE explicitly requests to deregister from the SMS using mobility registration, it will subsequently not send an SMS. This is not problematic, since this is a decision taken knowingly by the UE. However, when there is an event at the network end (e.g., the SMS removed from the UE's subscription in the UDM), it is not presently apparent how the UE is made aware of this status. Therefore, the UE will continue to try and send mobile originated. (MO) SMS, and the SMS message will fail. The UE may continue to keep trying to send the SMS. This can pose problems in terms of wasting UE resources, especially battery life and can otherwise waste system resources.

Effectively, it is possible that the UE is deprived of the ability to send SMS messages by network congestion. An issue then is that the UE is not informed by the network of this loss of capability. If the UE then attempts to send an SMS, any such attempt will fail.

The electronic device may be a combination of one or more of the aforementioned various devices. The electronic device may also be a flexible device. Further, the electronic device is not limited to the aforementioned devices, and may include an electronic device according to the development of new technology.

Hereinafter, an electronic device will be described with reference to the accompanying drawings. In the disclosure, the term “user” indicates a person using an electronic device or a device e.g., an artificial intelligence electronic device) using an electronic device.

When the UE requests the SMS in a registration request, and the AMF successfully allocates an SMSF and activates the SMS services towards the SMSF, it stores the SMSF address and an indication that “SMS is allowed” in the UI's 5G mobility management (5GMM) context.

When the UE requests the SMS in a registration request and the UE does not have an SMS subscription, the AMF cannot allocate an SMSF or the activation of the SMS service is not successful, then the AMF stores “SMS is not allowed” in the UE's 5GMM context.

“SMS is allowed” could occur by the AMF receiving notification from the UDM of subscription withdrawn, or (e.g., due to a 5GS to EPS mobility scenario) the AMF needing to invoke the SMSF to deactivate the SMS service or else the AMF considers the UE as deregistered. The UE may wish to re-register for SMS.

“SMS is not allowed” could occur by the AMF receiving notification from the UDM of subscription addition. The UE may wish to re-register for SMS.

The generic UE configuration update procedure known in the prior art is modified herein to include an “SMS changed” indication that will only get sent to the UE when the UE has previously requested the SMS in initial registration.

In the standards specification, TS 23.502 subclause 4.2.4 and TS 24.501 subclause 5.4.4 describes the generic UE configuration update procedure which allows the AMF to dynamically update the UE configuration for access and mobility management related parameters decided and provided by the AMF.

The parameters specified that can be updated are 5G globally unique temporary identity (5G-GUTI), tracking area identity (TAI) list, service area list, network identity and time zone, local area data network (LADN) information, rejected network slice selection assistance information (NSSAI), allowed NSSAI, configured NSSAI and mobile initiated connection only (MICO).

However, there is not an indication specified to indicate to the UE that the status of the SMS service has changed (e.g., the SMS has been deregistered in the AMF due to a network action (e.g., the SMS subscription withdraw in the AMF)). The present disclosure provides a modification to provide such an indication.

As such, the parameters which can be specified, a include 5G-GUTI, TAI list, service area list, network identity and time zone, LADN information, rejected NSSAI, allowed NSSAI, configured NSSAI, MICO and an indication that the status of the SMS service has changed.

Assuming that the LIE had previously requested to use the SMS and the network indicated “SMS allowed” or “SMS not allowed”, an “SMS change” indication is provided that will inform the UE that if it wants to use the SMS, it must first re-register and request the SMS again before attempting to send the SMS.

In particular, if the SMS was allowed before (i.e. “SMS allowed”), then the UE knows that it has to register again before submitting a new SMS. “SMS change” here means that submitting an SMS would fail. It is clear that SMS has been deregistered in the network.

If the SMS was not allowed before (i.e. “SMS not allowed”), then this trigger informs the UE to now try and register in order to send an SMS that it wished to send previously and was unable to. It is not mandated to register, but it may wish to try again.

In other words, an “SMS changed” indication requires the UE to take this information into account for internal operation, which may include the UE taking steps to re-evaluate and perform mobility registration before it decides to send the SMS the next time.

If the UE receives an “SMS changed” IE in a configuration update command message and the UE still wants to use the SMS, then the UE requests the use of the SMS by performing a mobility registration procedure as specified by the appropriate standard.

FIG. 1 is a diagram of configuration update command message content, according to an embodiment. The final entry illustrates the “SMS changed” indication. The above described configuration update command message format is simply an illustration of one way in which the network may indicate “SMS changed” to the UE. Other signals may be used as appropriate.

FIG. 2 is a diagram of an “SMS changed” information element (IE), according to an embodiment. The “SMS changed” entry in the table of FIG. 2 may be included to indicate a change in the UE's allowance to use the SMS if the UE previously requested the use of the SMS in the last registration procedure. This informs the UE that further steps may be required before the SMS can be used again.

The “SMS changed” IE is a type 4 information element with a length of 3 octets as shown in FIG. 2, As shown, “SMS changed” is indicated by bit 1 of octet 3 whereby if this bit is set to 0, the “SMS allowed” by the network has not changed, and if this bit is set to 1, then “SMS allowed” by the network has changed and the UE may be required to take further action. All the other bits in Octet 3 are spare and coded as 0.

As described herein, the present disclosure addresses the issue associated with a UE potentially sending repeated SMS messages when the network has changed the UE's allowance to use the SMS. By inserting a suitable indication in a message sent to the UE, the UE is able to re-evaluate its allowance to use the SMS and may act accordingly.

FIG. 3 is a diagram of a configuration of a user equipment, according to an embodiment. Referring to FIG. 3, the UE may include a transceiver 310, a controller 320, and a storage unit 330. The controller 320 may be defined as a circuit, an application-specific integrated circuit, or at least one processor.

The transceiver 310 may transmit/receive signals to/from other network entities. The controller 320 may control overall operations of the UE. The storage unit 330 may store at least one piece of information transmitted/received through the transceiver 310 and information produced through the controller 320.

The signal or the power may then be transmitted or received between the communication module 490 and the external electronic device via the selected at least one antenna. According to an embodiment, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module 497.

At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).

According to an embodiment, commands or data may be transmitted or received between the electronic device 401 and the external electronic device 404 via the server 408 coupled with the second network 499. Each of the electronic devices 402 and 404 may be a device of a same type as, or a different type, from the electronic device 401. According to an embodiment, all or some of operations to be executed at the electronic device 401 may be executed at one or more of the external electronic devices 402, 404, or 408. For example, if the electronic device 401 should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device 401, instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device 401, The electronic device 401 may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request. To that end, a cloud computing, distributed computing, or client-server computing technology may be used, for example.
